-the appendicular skeleton is the portion of the skeleton of vertebrates consisting of the bones that support the ‘appendages’-
.
(‘appendages’ appeared as ‘fins’ in early fish, and subsequently evolved into the ‘limbs’ of ‘tetrapods’)
(the ‘appendicular skeleton’ includes the ‘skeletal elements’ within the ‘limbs’, as well as supporting ‘pectoral’ + ‘pelvic’ girdles in the case of ‘tetrapods’ (these are lacking in fish))
.
(the word ‘appendicular’ is the adjective of the noun appendage, which itself means “a part that is joined to something larger”)
